Thank you for clarifying the purpose of the CHKDSK utility. Definitely cleaned up my understanding.

Q:
CHKDSK and Mirrored Drives
The following came up in a conversation today, and, it appears, that my Google-foo has gone on vacation.
The question that was raised was how does CHKDSK handle mirrored drives? Does it just check the active drive, or both the active and passive drive?
I am inclined to think that it only checks the active drive, being unaware that there is a passive drive. If this is the case, how would one do the occasional check of the passive drive for bad sectors, which could impinge upon the performance of the drive set?

If the RAID controller allows for reads from both disks in the mirror then all bets are off. When working with arrays it is better to use the array controller (or SAN) to check for bad sectors as the controller has access to the physical disks and can check them one at a time.
